Jmol 13.0 released

Jmol 13.0 was released Aug 22, 2012. This major release brings to the stable release several very important new features in Jmol developed over the past year.

With well over 500,000 full application downloads (that is, distinct binary downloads by application users or developers, not simple applet downloads by users), full server-side Java support for non-Java (iPhone/iPad) or non-applet (Android) mobile devices, and a completely new JavaScript interface, Jmol is well-positioned for the next phase of development of a high-level scripted high-functional HTML5/WebGL user interface. ... read more

Jmol 11.2 released -- over 50 new features

Jmol is a Java molecular viewer for three-dimensional chemical structures. Features include reading a variety of file types and output from quantum chemistry programs, and animation of multi-frame files and computed normal modes from quantum programs.

Jmol 11.2 introduces many new capabilities, including "flying" through the molecule in "navigation mode", internal (arbitrary plane) slabbing, surface cavity depiction, mapping of user-derived data onto surfaces, loading of files without replacing already-loaded files, variable translucency, the translating, rotating and inverting of selected atoms, the use of calculated mathematical values in all commands, and the writing of JVXL surface data directly to files.

Jmol 11.1 beta testing requested

Jmol 11.1 prelease development versions for Jmol 11.2 are in active late-stage beta testing. We encourage developers interested in the broader range of capabilities listed below to try Jmol 11.1.

Jmol 11.1 represents a revolutionary new way to work with and visualize molecular data.

A new navigation mode for Jmol 11.1 allows scripted or unscripted "fly-throughs" of the model. Fasten your seat belt and take a ride on a protein's backbone from one end to the other. ... read more

Jmol Voxel File Format (JVXL)

Jmol 11.0 introduces a revolutionary way of delivering molecular surfaces over the web -- the Jmol Voxel File Format (JVXL). With a compression ratio on the order of 300-600:1 over color-mapped CUBE files, the JVXL format allows delivery of full protein color-mapped solvent-accessible and solvent-excluded surfaces in 30-60 Kb instead of 10-20 Mb, making practical delivery of molecular surfaces available on the web for the first time ever.... read more

Jmol 11.0 -- over 100 new features

We recommend that all developers of new web pages utilizing Jmol upgrade to Jmol 11.0 if currently using Jmol 10.2.

Jmol 11.0 is a significant advance over version 10.2, including an extraordinary set of new features such as the ability to save and restore the state of the model, the ability to annotate a model by placing text at any {x y z} coordinate, the ability to select and remove atoms based on one or more defined planes, the capability to designate a particular model as a "background" model, custom stereo viewing coloration, the ability to define arbitrary space groups and unit cells for any model from any file format, even if that information is not contained in the file and the coordinates are not fractional, the option to recalculate secondary structure on the fly after selecting a specific set of alternative atom locations, and if/else/endif constructs in scripts. ... read more

Next stable release nearing completion

After a year of hard work by mostly one developer (Miguel) a new stable release is nearing completion. An active user community with lots of suggestions, ideas, questions, requests, patches helped a lot during the last year.

The new release features a completely rewritten Jmol while most of the old features are again available, including a much faster rendering engine, and much better scripting engine. ... read more
